Abstract

This paper presents recent work on a VLSI-Membrane-Mirror-Light-Modulator (VLSI-MMLM) for scene projection. This prototype spatial light modulator uses a membrane-mirror atop a custom very-large-scale integration (VLSI) chip to modulate an off-chip light source. This modulator offers flickerless frame rates in excess of 100 Hertz and an array size of at least 200 x 200 pixels. The modulator achieves a high-degree of compactness and portability and offers low power operation since it uses external sources of light. Preliminary images have been projected in both the visible and midwave infrared wavebands. This paper focuses primarily on the design, development, testing and performance of the custom VLSI chip required for this application.
